Testo 770-3 Clamp Meter - 0590 7703
Non-contact measurement on tightly packed cables is really easy and reliable with the testo 770-3 clamp meter. Its innovative grab mechanism enables maximum precision. As the most high-performance model in the clamp meter family, it offers many additional functions for your challenging daily tasks, such as the Bluetooth interface.
The testo 770-3 cable-grabTM clamp meter is the ideal clamp amperemeter for demanding measuring tasks in tight application environments. The movable pincer arm can be fully retracted into the instrument. This enables the instrument to grab tightly packed cables in a particularly accurate way.
In addition, more specialized applications can be handled using the clamp meter, such as starting current, power and µA measurements. And, as well as measuring electrical parameters, you can also check temperatures with the integrated temperature adapter for type K thermocouples.
The clamp amperemeter automatically detects and selects AC/DC and other parameters, such as resistance, continuity, diode and capacitance,. This makes operation easier and more reliable than ever before. Your readings are clearly and distinctly presented on the two-line display. The Bluetooth interface is also particularly practical, enabling you to connect other instruments to the clamp meter.
Key Features
Fully retractable pincer arm for maximum flexibility
Auto AC/DC and large two-line display
Measuring functions for starting current on electric motors and μA measurements
Temperature adapter for type K thermocouples
